Abstract

Et billeddannende ultralydsystem og en tilsvarende fremgangsmåte er fremskaffet for å frembringe harmoniske kontrastbilder med harmoniske komponenter frembragt ved hjelp av kontrastmiddelet og med liten forstyrrelse fra ikke-lineær vevpåvirkning. Det er beskrevet en fremgangsmåte for å utvikle forhåndsforvrengte ultralydsendesignaler, hvis forhåndsforvrengning vil bli motvirket på grunn av vevets ikke-lineære virkninger for så å gi hovedsakelig lineære bølgeformer på det sted hvor kontrastmiddelet befinner seg. Ekkoene som sendes tilbake fra kontrastmiddelet vil inneholde ikke-lineære komponenter som stammer fra samvirket mellom den lineære bølgeform og middelet, og som har minskede ikke-lineære komponenter som skyldes ikke-lineære vevvirkninger.An imaging ultrasound system and a corresponding method are provided to produce harmonic contrast images with harmonic components produced by the contrast agent and with little interference from nonlinear tissue influence. A method is described for developing pre-distorted ultrasound transmit signals, the pre-distortion of which will be counteracted by the non-linear effects of the tissue, so as to produce substantially linear waveforms at the location of the contrast agent. The echoes sent back from the contrast agent will contain nonlinear components resulting from the interaction between the linear waveform and the agent, and which have reduced nonlinear components due to nonlinear tissue effects.
